I have a question about mixing a matching objectives an eyepieces.
I have a few old Olympus microscopes in the 1950-70s era
I have just purchased a nice BHB Olympus microscope. Images though it look ok, but not great. I still have clean it up, its very dusty.
The BHB is a lower end research grade DIN scope with tube length of 160mm
Looking at Alan Woods excellent site
I see that it was designed for objectives with a parfocal distance of 36.65mm
However the objectives and eyepiece on the scope look to be for a BH-2 which has a parfocal distance of 45mm
eyepieces are 2x WHK 10x/20 L, NFK 3.3x photo eyepiece
objectives are DPlan 10-40 160/0.17
My reading of the standards is that the 160mm tube length is from the objective mounting flange to the eyepiece flange.
So am I right in thinking that as long as I match the 45mm objective with the WHK eyepieces (i.e they way it came) then all will be well?
Or is there something in the design of the prisms of the BHB that makes it necessary to obtain the 36.65mm objectives to get the best performance?
i.e should I be looking for a BH-2 to match the objectives I have, or a set of 36.65mm objectives/eyepieces, or can I sit as is.
The images are fine visually, but I want to set it up as a photomicroscopy platform and so want to get it right.
